Open Wiki is prone to a cross-site scripting vulnerability. This issue is due to a failure in the application to properly sanitize user-supplied input.
An attacker may leverage this issue to have arbitrary script code executed in the browser of an unsuspecting user in the context of the affected site. This may help the attacker steal cookie-based authentication credentials and launch other attacks.
UPDATE (September 12, 2008): Additional information suggests that this issue may not exist.
Open Wiki 0.78 is reported vulnerable. Other versions may be affected as well.
